To all whom it may concern:

Be it known that we, VVILLIAM H. lVTAR- GERISON and. ALBERT E.MARoERIsoN, of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inDouble-Faced l/Voven Fabrics, whereof the following is a specification,reference being had to the accompanying drawings.

Our invention relates to a double-faced single ply terry weave, such asmay be employed in toweling, and the object of my invention is toproduce a fabric in which the loops are more firmly locked or an choredin position than has heretofore been the case in fabrics of a similarcharacter, thus preventing the unraveling or pulling out of said loops.

In the accompanying drawings, we have illustrated a view in perspectiveof a fabric embodying our invention, the threads being unduly separatedin order to render the structure more easily understood.

The warp threads consist of two classes, namely, the loop warps 1, and3, and the binder warps 2, and 4. These may alternate with each other asshown, or be otherwise interrelated.

The loop warps are of two sorts, according as their loops project fromone side or the other side of the fabric. As we have illustrated thefabric in the drawings, these alternate with each other. As in terryweave of this general character, the loops are beaten up as the fabricis woven, this action being permitted by the slackening of the loopwarps as they are fed. WVhere the loop is formed, the loop warps passover or under two picks, and both the upper and lower loops are formedalong the line of the same two picks, whereby a complete course of loopsalternately on the face and back of the fabric, is formed crossing itswidth coincident with these two picks, which may be termed the looppicks. These loop picks recur at intervals of six picks, that is to say,there are four picks between each pair of loop picks, the first of saidfour being the pick by which the loops are beaten up, and the otherthree constituting binding picks, whereby the loop warps are more firmlyinterwoven with the picks during the intervals between the loops, thanis the case in a similar fabric where the loops recur without theinterposition of these three picks for interweaving purposes.

teferring to the drawing, 15, and 16, and again 22, and 23, constitutethe loop picks; 17, and 2d, are the immediately succeeding picks, bywhich the loops are beaten up, and 18, 19, and 20, are the intermediatepicks for the purpose above specified. It will be ob served that in theinstance which we have shown these intermediate picks are woven as atwill, but our invention is not dependent upon the exact nature of thisintervening weave, but is distinguished by the fact that in addition toand interspersed between the three picks which are essential to theconstitution of each loop course, (to wit the two loop picks and theimmediately succeeding pick), there are interposed a plurality of picks,preferably three, forming a weave which tends to interlock or anchor theloop warps, so as to prevent tension upon a loop pulling it out at theexpense of the adjacent loops of the same Warp. But it will beunderstood that our invention is not confined to the precise weaveillustrated in the drawing, but includes other similar weaves in whichthe same purpose is accomplished, to wit, the anchorage of the loopsformedby the loop warps.

Having thus described our invention, we claim:

1. In a single ply terry weave the combination of loop warps and binderwarps in suitable alternation with each other; a plurality of Weftthreads constituting loop picks interwoven with said binder warps; aloop beating pick crossing each binder warp on the same side as the lastloop pick and crossing on alternate sides of successive loop warps; anda plurality of binding picks forming a twill weave with the loop andbinder warps.

2. In a single ply terry weave the combination of loop warps and binderwarps in suitable alternation with each other; a plurality of weftthreads constituting loop picks interwoven with said binder warps; aloop beating pick crossing each binder warp on the same side as the lastloop pick and cross ing on alternate sides of successive loop warps; anda pair of binding picks interwoven with and crossing the respective loopwarps on the same side, but crossing the binder warps on opposite sides.

3. In a single ply terry weave the combination of loop warps and binderwarps in suitable alternation With each other; a plurality of weftthreads constituting loop picks interwoven with said binder warps; aloop beating pick crossing each binder warp on the same side as the lastloop pick and crossing on alternate sides of successive loop warps; apair of binding picks interwoven with and crossing the respective loopwarps 0n the same side but crossing the binder warps on opposite sides;and a third binding pick crossing each binder Warp on the same side asthe second binding pick crosses that binder warp, but crossing each loop15 Warp on the side opposite to that on which said second binding pickcrosses said loop Warp.

In testimony whereof, We have hereunto signed ournames, at PhiladelphiaPennsyl- 20 Vania, this sixteenth day of July 1907.
